leptospirosis is a zoonotic disease with global distribution that caused by pathogenic spirochetes of the genus leptospira. accurate diagnosis for differentiation of leptospirosis from other pyrogenic infections prevailing in the same locality and is imperative for proper treatment. therefore a molecular diagnostic test with high specificity and sensitivity such as pcr is essential. gene encodi...

conclusion according to our findings, it is recommended to use ferula gummosa extract, as a herbal alternative treatment, in more investigations to prove its treatment effects on infections. objective ferula gummosa grows as a native plant in different parts of iran and has been used for treatment of some infections such as uti since ancient times. present study is planned to show the antibacte...

aim :  the aim of this study was to investigate the in vitro inhibitory effect of probiotic e.coli nissle 1917 (ecn) strain against pathogenic bacteria isolated from patients with diarrhea. background : probiotics are viable microorganisms that are shown to have beneficial effects on human health. ecn is a typical example of probiotics; however, there are few reports of it being administered fo...

conclusions the results showed that some patients were probably contaminated with nonbacterial and nonparasitic agents. all the parasitic isolates were resistant to most antibiotics. therefore determination of microbial isolates and antibiotic susceptibility is necessary before treatment procedures. results of 2376 patients, 466 (19.6%) were contaminated with pathogenic bacteria or protozoa.the...

background: masske is a traditional iranian butter made from yoghurt. the first aim of this study was to isolate and identify the nonlactic pathogenic microflora by culture and molecular methods of identification, and the second purpose was to identify genetic similarity of the isolated bacteria in masske. materials and methods: in order to detect pathogenic dominant indicator microorganisms, a...

conclusions chlorine-stressed cells of v. parahaemolyticus were more susceptible to adverse conditions than the non-stressed ones. pathogenic and non-pathogenic strains showed the same survival characteristics under the adverse conditions. these results should be considered in the development of food preservation measures. results findings of the current study revealed that the normal cells of ...

abstract background: the functions and use of mouthwashes are variable depending on their type. oral care in patients with endotracheal tubes is important to prevent side effects such as pneumonia. the aim of this study was to determine the antimicrobial effects of chlorhexidine, drop of matrica mouthwash (chamomile extract), and normal saline on hospitalized patients with endotracheal tube in ...

objective(s):urinary tract infection (uti) caused by bacteria is one of the most frequent infections in human population. inappropriate use of antibiotics, often leads to appearance of drug resistance in bacteria. however, use of probiotic bacteria has been suggested as a partial replacement. this study was aimed to assess the antagonistic effects of lactobacillus standard strains against bacte...

screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. actinomycetes have the capability to synthesize manydifferent antibiotics. a total of 69 actinomycete isolates were recovered from soil samplescollected from alborz province. selected colonies (rough, chalky) of actinomycetes werepurified. all screened isolates were iden...

background: avian pathogenic escherichia coli (apec), which is the causative agent of colibacillosis, harbors several putative virulence genes. an important trait of apec for both poultry and public health is antibiotic resistance. objectives: in the present study, some potential virulence genes of apecs isolated from northeast of iran and their resistance to the quinolones antibiotics were stu...
